Reliable bridging

While the district heating pipeline is being laid at the major construction site at Leipzig Central Station, a mobile heating container from Hotmobil is taking over the heat supply to the neighboring Deutsche Bahn operations center.

With the construction of the new central remote bus terminal, a major project planned many years in advance was launched in March 2017. Private investors are contributing 15 million euros to the project. The building will cover an area of 11,000 square meters, with eleven bus piers on the first floor and a parking garage with 550 spaces above. Also planned are, for example, numerous small stores, bicycle and car rentals, and lockers. In addition, two hotels with a total of 530 rooms are to be built in the immediate vicinity. These represent an investment volume of another 55 million euros. The reason for the expansion is, on the one hand, the increasing number of long-distance trips by bus, and on the other hand, there is a lack of space for the buses as well as for the passengers at the Leipzig stop in Goethestraße.

Extensive civil engineering work is necessary for the new construction. In order to carry out this work, technical project manager Arndt Kübler had to find a temporary solution for a district heating line that had to be relocated. This supplies the neighboring main building of the south-east rail operations center. From there, the rail network throughout central Germany is controlled in three-shift operation. "This building is considered extremely sensitive. The heat supply must be guaranteed 100 percent," reports the project manager. He was supported in his search by his specialist planner, who drew his attention to the nationwide service provider Hotmobil. Here he found the right solution: a heating container with 1,500 kW plus a 7,000-liter oil tank. From there comes the heat supply, which is planned until late fall. After he had made the agreed preparations and, among other things, had the necessary threads fitted, the heating container could be connected directly to the district heating network within a very short time. Initial concerns about possible noise pollution quickly turned out to be unfounded, as the Hotmobil large-scale plant is optionally equipped with a powerful silencer that reduces noise emissions by another 10 decibels. Arndt Kübler continues: "Unfortunately, I do not have my own personnel available for monitoring the temporarily used heating system. That is why I am particularly grateful for the special equipment of the container. The automatic fault indicator and the tank monitoring are extremely helpful - especially because contamination of the oil filters can never be ruled out and we also need a new tank filling approximately every seven days. All in all, I am very satisfied with the advice, the support of the fitters from the Leipzig branch of Hotmobil and the system including additional equipment. The coordination of the decommissioning and the collection of the plant was also organized with the Hotmobil headquarters in an extremely constructive and flexible manner."
